Wow, very nice! I wanted to comment on these at work today, but was so darn busy. I'm very glad to see you here, and your work is very, very good!
Obi Wan - That is very well done. I think the recipe for this is cool, and you executed it very well. I'm already seeing some of your other customs that I think I want to copy off of you too.
SaeSee Tiin - That's just awesome. Very well executed, and I like how the helmet is used and cut to fit him right, he looks so much more tough with it on. And even without it it looks fantastic. What kind of paint did you use? The armor looks great.
Ki Adi & Plo Koon - The parts swaps are very well done, and really are a good fit for these guys. Again, great work.
Aayla - Interesting concept here. I think this is one I'd be afraid of trying, just because it's so hard to get the manly armor to look feminine. But you made a good effort at it and it looks nice. It might be possible to use VOTC Stormtrooper parts to make her look a little less bulky, but even as it is, it's still very cool.
Good painting and parts using all around. I would suggest maybe a small amount of weathering, but that's entirely up to you. Great update!
